Special shortwave transmissions to North Queensland due to Cyclone Yasi


Category 5 Tropical Cyclone Yasi will hit the northern Queensland coast between Cairns and Townsville within the next few hours. Much damage to houses, property and infrastructure is anticipated within this area when the cyclone hits the coastline. Flooding and very high winds will also be a major problem for those people who haven’t managed to leave the area. Because of this the local ABC and commercial broadcasters expect severe damage to landbased TV and radio transmitters within the region. The ABC has requested Radio Australia to transmit the ABC’s northern Queensland regional radio service using a shortwave transmitter at Shepparton, Victoria to northern Queensland until further notice.

The Australian Bureau of Meteorology is forecasting that Tropical Cyclone Yasi will hit land around 1200 to 1400 UTC and then produce a very large rain depression which could see around 350mm fall into northern and central Australia.

Schedule

*2100-0830 UTC on 9710 kHz 353deg
*0830-2100 UTC on 6080 kHz 005deg
The transmitter being used is a brand new 100KW Continental which is DRM capable.

American Radio Stations in Australia

Some time ago, we presented the story of the American shortwave station in Australia that was established under General Douglas McArthur for communication with American units in the Pacific and in the continental United States. This shortwave transmitter facility was established at Hemmant, which is an outer suburb of Brisbane in Queensland, and it was on the air for a period of three or more years with the usage of several units, including a 10 kW Federal transmitter and a 40 kW Press Wireless transmitter. The shortwave receiver station was located half a dozen miles distant, in another outer suburb, Capalaba.
It is true that this double station was established primarily for armed forces communication purposes during the latter half of World War 2. However, there were many occasions when it was in use for the forwarding of news information to the United States, and even voice reports for re-broadcast by the mediumwave networks in the United States.
Since the researching and writing of this topic, we have discovered that there was a whole network of at least ten of these American communication stations in Australia, beginning in the year 1942. These stations were used mainly for teletype transmissions, as well as for communications in high speed Morse Code.
The very first of these American radio stations in Australia was installed in a suburb of Melbourne, the capital of the south eastern state of Victoria. This unit became operational on March 10, 1942, just two weeks before General MacArthur arrived in the city by train. The Melbourne station was a joint operation between American and Australian personnel, and under MacArthur, it was in service under the American callsign WTJJ.
This Melbourne station, WTJJ, received messages from the Philippines and elsewhere via WVJK in Darwin and forwarded them on to the United States via the army station WTJ in Hawaii. In view of the long range transmission from WTJJ Melbourne, we would presume that this transmitter was rated at least at 10 kW, and probably more likely at 40 kW.
It was around this time that another temporary station was installed, this time in a railway train, for use in various areas of eastern Australia. The train facility was made up of teletype transmitters, probably three of them, rated at 3 kW and manufactured by Hallicrafters for use in airplanes.
Another one of these stations was installed in Sydney, New South Wales and this was on the air under the American army callsign, WVJM. This station communicated with American army communication stations located in Melbourne, Brisbane and Townsville.
In the north eastern state of Queensland, three more of these American radio stations were established for communications within Australia and beyond. These stations were located in Brisbane and Townsville.
Initially, the first Brisbane station was installed temporarily in a tent on the Redlands Bay Golf Course, some distance north of Brisbane itself. A substantial building was quickly erected and it housed a 10 kW Federal transmitter with 5 rhombic antennas nearly one hundred feet tall.
Another temporary station with a 1 kW Federal transmitter was installed in the girl’s high school at Somerville House Brisbane for communication with Sydney and Townsville. The two temporary stations in Brisbane, Redlands Golf Course and Somerville House, were closed in February 1943 when the more substantial facilities at Hemmant and Capalaba were inaugurated.
The American communication station WVJL in Townsville in northern Queensland, was located adjacent to the Coastal Radio Station, which housed the transmitters for the AWA maritime station VIT and the local mediumwave broadcast station 4TO. During this era, VIT-4TO communicated with VIG Port Moresby as part of the wartime Coast Watch service. The Port Moresby transmitter was the old mediumwave unit, 4PM, which had been converted for shortwave telegraphy usage.
In the Northern Territory, there were two American shortwave communication stations, one near Darwin itself right on the north coast, and the other at Adelaide River, 75 miles inland. The Darwin station was identified as WVJK, and the inland station as KAZ. The inland station initially handled all American traffic from the Philippines, and in 1944 it was transferred to Hollandia in Dutch New Guinea; but that’s another story for another time.
Suffice it to say that each of these ten known American communication radio stations handled communication traffic, as well as at times, media messages for broadcast and publication. The stronger stations, and in particular the 40 kW unit on the edge of suburban Brisbane, also carried voice messages for relay on mediumwave throughout the United States.

American Radio Stations in Australia – Gnangara in Western Australia

On previous occasions here in our DX program, “Wavescan”, we have presented the story of four different American radio stations located in Australia; General MacArthur’s shortwave station installed on a train and a fixed station located at Hemmant in Queensland, the RCA lendlease transmitter at Shepparton in Victoria, and the AFRS usage of the ABC mediumwave station 4QR in Brisbane. On this occasion here in “Wavescan”, we continue in our series of American radio stations in Australia, and we feature the shortwave station located at Gnangara near Perth in Western Australia.
Actually, Gnangara is an aboriginal place name, and it means: the place where yams grow. This is an outer suburban area, just fifteen miles north of Perth and just ten miles south east of Wanneroo, which was the original location for the now silent ABC shortwave stations VLW & VLX.
The Commonwealth Government procured 320 acres at Gnangara in 1952 for the purpose of establishing an international shortwave communication station. This large tract of land was then transferred to OTC, the Overseas Telecommunication Commission fourteen years later, and then it was that work commenced on establishing a shortwave communication station on behalf of NASA, the American space agency. Some electronic equipment installed at this new shortwave station was new, and some was transferred from redundant NASA facilities in South Australia, and at Carnarvon in Western Australia.
The Gnangara station was established primarily for electronic communication with Mauritius during the series of Apollo space flights and moon landings from 1967 to 1975. Mauritius was considered to be one of the likely splashdown areas for the return of some of the Apollo space flights. Three shortwave communication transmitters at 7½ kW were installed at Gnangara with rhombic antennas oriented towards Mauritius. Landline communication to Moree in New South Wales completed the Australian circuits in the Apollo space program.
Although the Gnangara radio station was primarily an American NASA project, yet it was staffed by Australian personnel. The NASA usage of Gnangara was terminated around the beginning of 1975 at the successful conclusion of the Apollo space flights, and the Australian shortwave communication services were transferred from Gnangara to the OTC facility VIP at Applecross. Thus, the Gnangara station was now inactive.
In the meantime, Radio Australia was looking for a suitable site for a new and supposedly temporary shortwave station to fill in for the Darwin station which was disabled by Cyclone Tracy on Christmas Day, 1974. In order to once again test the viability of an international shortwave station in Western Australia, OTC engineers turned their attention to the recently inactivated shortwave communication station at Gnangara. They modified two of the 7½ kW communication transmitters for the broadcast of radio programming and a two week series of test transmissions began on February 25, 1975. These test transmissions consisted of music and test announcements in English which had been recorded in the Melbourne studios of Radio Australia. In two sets of daily transmissions, these test broadcasts were beamed to South Africa, Indonesia, and England with the use of rhombic antennas. Monitoring reports indicated good signals in several countries of Asia, and beyond.
Although reluctant to do so at first, Radio Australia did issue many QSL cards to verify the reception of these test transmissions. The Indianapolis collection contains two of these regular Radio Australia QSL cards, endorsed with the transmitter location, “Perth”.
As a result of the successful series of test broadcasts from the NASA station at Gnangara, plans were implemented for the establishment of what was intended to be a temporary relay station for Radio Australia, at Carnarvon, on the continental west coast.
And that’s a story for another occasion. But what happened subsequently to the NASA shortwave station at Gnangara? Four years after the series of test broadcasts, a small group of international radio monitors representing the Australian Radio DX Club made a visit to the Gnangara radio station and they found it active as a communication facility, VIP, for shipping in nearby coastal waters, and for outback communication with isolated areas in Western Australia. Three years later again, electronic equipment from the Australian earth station at Carnarvon was installed at Gnangara, and four years later again, a cable service connecting Australia to Asia was opened.
For a short time in 1994, a mediumwave station operated by Australian Aborigines was installed at Gnangara; two years later, VIP Gnangara operated the coastal station VID in Darwin by remote control, and in 2001 the cable service with Asia was superseded by satellite communication, and in 2002 the Gnangara shipping station VIP was decommissioned.
Last month, during the month of July, Gnangara was in use for the reception of signals from a communication satellite launched from an ocean platform at the equator; and the transmitter tower for the ABC mediumwave station 6WF is located nearby. However, with the rezoning of the nearby areas for housing, it looks as though the end of the Gnangara radio station is coming soon. Nevertheless, Gnangara will always be remembered in the international radio world as an American NASA shortwave communication station that was in use for a two week period in 1975 as a test facility on behalf of Radio Australia.
